A New Therapeutic Approach for Root Coverage

2014-07-23 21:08:47 | BioPortfolio

Summary

Different surgical techniques have been proposed for root coverage, showing varying results especially in areas of deep recessions. The aim of this study is to evaluate the effectiveness of the newly forming bone technique (NFB)as an alternative treatment for Miller class I or II deep recessions, requiring regeneration of lost periodontal tissues. Sample should be comprised of patients aged 18-45 years, both genders, presenting at least one site with marginal tissue recession >4mm. Patients will be randomly assigned to either one of the groups, based on treatment technique: newly forming bone (NFB) or subepithelial connective tissue graft (SCTG). Clinical examinations will be performed by a single blinded examiner at baseline, 1, 3, 6 and 9 months after surgery. Intra-group analysis will be performed by one way analysis of variance for repeated measures. Inter-group analysis will be performed by unpaired t-test for each of evaluation periods.

Medical and Biotech [MESH] Definitions

A surgical technique to correct REFRACTIVE ERRORS of the EYE, such as MYOPIA and ASTIGMATISM. In this method, a flap of CORNEAL EPITHELIUM is created by exposure of the area to dilute alcohol. The flap is lifted and then replaced after laser ablation of the subepithelial CORNEA.

Dense fibrous layer formed from mesodermal tissue that surrounds the epithelial enamel organ. The cells eventually migrate to the external surface of the newly formed root dentin and give rise to the cementoblasts that deposit cementum on the developing root, fibroblasts of the developing periodontal ligament, and osteoblasts of the developing alveolar bone.

The fibrous CONNECTIVE TISSUE surrounding the TOOTH ROOT, separating it from and attaching it to the alveolar bone (ALVEOLAR PROCESS).

Removal of mineral constituents or salts from bone or bone tissue. Demineralization is used as a method of studying bone strength and bone chemistry.

A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
